Radically reducing freezer downtime: the CleanFREEZE takes centerstage

Aiming to optimize freezer production by minimizing cold-to-cold downtime, while making sure no shortcuts are taken on hygiene and cleaning? JBT Northfield’s CleanFREEZE marks a step-forward from the long-established Northfield SuperTRAK Structure Supported Spiral Freezer by delivering a radically-reduced cold-to-cold time, along with important hygienic and ease-of-maintenance innovations. 

At its core, the CleanFREEZE takes the original SuperTRAK design and adds new hygienic features, including innovations that differentiate the CleanFREEZE freezer from other spiral freezers currently available. The comprehensive redesign not only minimizes the defrost full sanitation process, it also makes the freezer easier and quicker to clean, and reduces the risk of bacterial contamination.

Turnaround time
Perhaps most significantly, the cleaning turnaround time has been cut to four hours from an industry average of six. In the process, says John Bauer, JBT’s Freezer Division Product Manager, customers will be able to make real savings on time. “With the CleanFREEZE, customers don’t have to go through such a lengthy cleaning process so they can increase production and throughput, enabling them to maximize uptime,” he says.

Ease of maintenance
However, the time savings aren’t just limited to the cleaning process. The latest version of the CleanFREEZE features significant improvements to ease-of-maintenance, including the moving of fan motors to the exterior of the structure. “Having the fan motors outside allows customers to replace them easily if something fails while they continue to run production,” explains Bauer. “We’ve also added stairs to enable easier access to the mezzanine level, so the maintenance crews can have quicker, safer access to components on the mezzanine level, behind the coils and other areas.”

More than this, JBT has improved hygienic features across the CleanFREEZE, minimizing overlapping surfaces throughout its open-profile framework, and adopting capless rails. 

Customers will be able to learn firsthand about the CleanFREEZE at IPPE 2022, the International Production & Processing Expo, which takes place in Atlanta GA from January 25-27, 2022, where JBT will be highlighting its commitment to customers: “We’re with you, right down the line”™.

JBT will be exhibiting at IPPE 2022 in Atlanta GA from January 25-27 in Booths C12743 and C12943 at the Georgia World Congress Center.

JBT freezer upgrades: growing capacity as your business grows

plant growing

Efficient, effective freezing solutions that last decades are a JBT speciality, but as your business grows and develops, there comes a stage when more capacity is needed. However, spending on a new machine is not always necessary. JBT’s retrofit- and upgrade program can bring older freezers into the modern era in a quick, safe and very cost-effective way. 

JBT offers upgrades to existing equipment, from replacing old, galvanized coils with stainless steel versions and improved, more efficient fans to the innovative Internet-Of-Things solution iOPS, which provides an integrated, connected overview of all systems. As an optional extra, JBT’s ADF (Air Defrost) system – for tackling snow build-up in freezers – enables producers to run for longer periods between defrosts and cleaning.

“If it is time to increase capacity, we can extend the belt to get more production through the freezer,” explains JBT Technical Solutions Manager, Robin Wachmann. “We can also replace coils, moving from old, galvanized versions to stainless steel, which offers improved safety and higher capacity. Stainless steel coils will also give you security against future rust attacks which can lead to refrigerant leakage.”

Cost-effective
But how easy is it to upgrade older freezers? JBT engineers can modernize old freezer units with upgrades like an improved, automatically air-balanced fan system and connectivity to JBT’s iOPS system. Other additions, such as a fan motor frequency convertor, mean customers can save energy – and money – by slowing fans when 100% speed is not required.

An upgrade or retrofit also offers significant advantages if space is at a premium or a new freezing solution is urgently required. “Sometimes when newer equipment is going to take up a larger space in a facility or if time is at a premium, an upgrade can be a good option,” says Wachmann. “An upgrade can further be very cost-effective because often the whole line is made for a certain volume of production and therefore if they just repair the existing one, everyone knows how to handle it and they know what they get.

“There’s a strong safety element to upgrades,” he adds. “With many old freezers, you can open the doors and go right into them. That is obviously not really up to today’s safety standards, so we can provide customers with an upgrade kit including a safety lock on the door and service handles.”

Need to save money on refrigeration and add space? Meet the LVS

Looking to reduce energy consumption on freezer usage while at the same time increasing capacity? In response to a strong demand from protein customers for refrigeration solutions that meet both requirements while at the same time offering more direct control, JBT’s LVS Refrigeration™ System now offers a solution which can be retrofitted on almost all existing Frigoscandia freezers.

JBT understands the need to reduce energy consumption and save energy, and with this in mind has engineered the LVS Refrigeration System for low energy consumption and optimum freezer performance. However, the benefits of the LVS don’t only end there: the system offers substantial economic advantages, with the chance to reduce your refrigerant charge by up to 50%.

Improved efficiency
“With an LVS, you can reduce energy consumption and increase freezer capacity, which are linked together,” explains JBT Refrigerant Development Engineer Håkan Ohlsson. “You also have a reduced ammonia charge, as well as more direct control over the system.”

By having the separation of liquid and gas done close to the freezer – and not far away as in a traditional pump system – typical production capacity losses are only total 0.5% compared with between 3-5% for a pump system, says Ohlsson. “Every degree C loss is equivalent to 3% loss in freezer performance, so it’s a huge difference,” he adds.

In fact, JBT LVS Refrigeration units are up to 20% more efficient than traditional pumped refrigerant systems with a patented dry suction system that delivers more capacity from the compressor and enhanced evaporator performance; all adding up to greater freezer capacity.

Enhanced sustainability
Another significant advantage offered by the LVS is its ability to deliver an enhanced sustainability performance compared with most traditional systems. Although additional safety equipment and training is required, JBT recommends the use of ammonia with the system; a neutral gas, which has zero global heating impact. However, even in instances where CO2 is used, the LVS enables customers to reduce the charge and thus the overall environmental impact.

Retrofitting is another important feature available through the LVS, with the system designed so that almost any JBT Frigoscandia freezer can be converted. The principal benefits of the LVS, continues Ohlsson, can be summed up as reduced losses and charges, savings of space in the engine room and reduced energy consumption, plus the option of connecting additional compressors directly to the system. “Through valve control, we can control the refrigeration both for cooling, defrosting and drying, so the freezer performs as well as possible,” he says.

“It is an obvious thing for JBT to help customers improve their sustainability, and therefore development of our LVS system is important – and clearly outlined – in the JBT strategy,” Ohlsson concludes.
